BOILER-COMPOUND HOLDER.

Specification of Letters Patent. Patented Apr. 15, 1919.

Application filed August 12, 1918. Serial No. 249,589.

The present invention relates to an im-- proved type of boiler compoundholder, which is particularly applicable for use 1n steam boilers fordispensing the chemicals used to soften the water being used. The

primary object of the invention is to provide a simplified device whichis easily manipulated and adapted for use in connection with boilers ofvarious sizes or for softening diiferent quantities of water, which isdurable, comparatively inexpensive in cost of production andmaintenance, and efficient in furnishing to the water to be treated auniform and regulated supply of material as required. i

With these ends in view the invention consists in certain novelcombinations and arrangements of parts as will be hereinafter more fullypointed out and set forth in the claims.

In the accompanying drawings I have illustrated the construction of theinvention according to the best modes I have so far devised for thepractical application of the principles of my invention.

Figure 1 of the drawings is a central vertical longitudinal section ofmy invention.

Fig. 2 isan end view of Fig. 1 taken from the right of same.

Fig. 3 is a cross-sectional view taken on line 3-3 of Fig. 1.

Fig. 4 is a detail view of a portion of the outer casing taken on line4.-4 of Fig. 2.

Fig. 5 is a side elevational view partly in section of a modified formof the device, showing an inner rack or crate designed to hold a numberof receptacles containing chemicals. Fig. 6 is a cross-sectional view ofFig. 5

' taken on line 66 of Fig. 5. v

Fig. 7 is an end view of Fig. 5taken from the right of same. I 1

Figs. 1 to 4 inclusive of the drawings show more particularly thepreferred form of the device, and Figs. 5 to 7 inclusive a modified formof the same;

.The numeral indicates a preferably cylindrical metallic tubularopen-ended barrel designed to receive a number of inner receptacles 2 ofsimilar cross-sectional form and adapted to contain a suitable boilercompound (not shown). The ends of the barrel 1 are closed by plugs orheads 3, which are provided with an annular inwardly turned flange 4 ofproper size to fit neatly the inner peripheral face ofthe said barrel 1.Securing means for the heads is provided by means of thin metal strips 5which are riveted to the inner wall of the barrel 1 at 6, and after theheads 3 are in place in the ends of the barrel, the strips 5 are bentover the, said heads at 7 thus securely fastening them in position. Itwill be seen that the rivetsv 6 are placed in the barrel 1 at the properpoints longitudinally so that the edges 8 of the flanges 4 just bearagainst the inner heads of the rivets 6, so that the latter formconvenient stops for the heads 3. As shown in Fig. '3 the flanges 4 ofthe heads 3 have to be slightly flattened at 9 to pass over the strips5, but as the latter are made of tin their thickness is negligible.Attention is called to the fact that the barrel 1 is made preferably ofheavier metal such as steel or wrought pipe, while the heads 3, andmetal strips 5, and the inner cylinders 2, are made of thin metal suchas tin. In connection with the cheapness of production of the device itmay be stated that the inner cylinders or receptacles 2 can be made ofthe ordinary tin cans, or even second-hand or usedtin cans can be used,and the heads which have been opened in use can be resoldered shut afterhaving been loaded with the chemicals used for softening the water, thusmaking the cost for inner receptacles very small. After the chemicalscontained in the receptacles 2 have been dissolved and dissipated in amanner to be explained below, the outer barrel 1 can be reused by merelyrenewing the metallic strips 5, in case the latter have been injured atthe point 7gby the bending which is necessary at this place.

Owing to certain ebullition movements of the water in the boiler (notshown), it

ment with the bottom of the boiler. 4 A bolt 7 12 clamps the bandtightly around the barrel 1. If desired two such bands 10 can be usedwhen it is necessary for the holder to be in a horizontal position, one"such being placed near each end. Each of the plugs or heads 3 isprovided with perforations 13, one or more, at the right or elevated endof the barrel 1, and another (usually a single) perforation l-l at theoppositeor less elevated end'of the barrel. The purpose of theseperforations is to admit the Water being softened by the chemical toenter the tube 1 at 14c and escape therefrom at 13, carrying with it thedissolved chemicals. Similarly each inner chemical containingreceptacle2 is provided with perforations 15, and 16 (see Fig. 3), correspondingto perforations 13 and 11 of the barrel 1, and for a similar purpose. Itwill thus be seen that the water enters the barrel 1 at 14, thenceentering each of the inner receptacles 2 at 16, loosens some of thechemicals Within the same and carries them through theperforat-ions 15into the mixing spaces 17 between and around the inner receptacles 2. Inthis connection it is noted that the receptacles 2 are maintained inspaced relation with respect to each other by means of the frictionbetween the outer surfaces of the said receptacles 2 and the interiorsurface of the barrel ;1 andit is evident further that as sediment isdeposited from the water of the boiler, between the receptacles 2 andwithin the barrel 1, the spacing shapes or mixing chambers 17 arereadily maintained between the ends of the receptacles. After being morecompletely dissolved and mixed for a short period in these mixing spaces17 within the barrel 1, the now thoroughly dissolved chemicals, andwater are carried out through the perforations 13 inthe end plug of thebarrel into the boiler. The-interior of the barrel 1, in this wayperforms the, function of a mixing chamber, where the chemicals arebroken down into molecules which are more readily assimilated when theyare later discharged into the boiler itself. It is noted in thedrawings, thatthe-interstices or spaces 17 between the ends of theadjacent inner receptacles 2, 2, etc, and also the space between theperimeter of the innerreceptacles 2, and the inner circumference ofthebarrel 1, as clearly shown in the Fig. 3 of the drawings, have been madeofconsiderable size for the purpose of affording the necessary mixingspace for the chemicals and water, prior to theiridischarge intotheboileritself. The amount of chemical bei'ng used can be controlled bymaking asin'an'y perforations 15, and 13, etc., as 1s foundnecessary-,but

inpractice it is found-only one perforation atlpo1nts14t, and 16"isnecessary, while two ,or three at 15 and, 13 give; the best results,

for ordinary sized boilers.

, the device.

In Figs. 5, 6 and 7 I have shown a'rack or crate 18 composedof; four ormore longitudinal strips of metal, 19, 2d of thin material preferably,and secured by two or more metal bands 20 riveted to same as shown. Atone-end of the rack 18, the strips 19, 2% cross each other as showndotted at 21-Fig. 7, Whileat theopposite end the strips are bent over asat 22, after the inner chemical receptacles 23 have been placed in therack injsimilar fashion to that described in connection withthe barrel1.

It Will'be seen that the charged racklS can "belplaced'i'vithin theouter barrel. 1, as shown in Fig. 5, the purpose of the rack being forconvenience in loading andshipping purposes. It will'be understood thatperiodically the devicehasto be reloaded with inher receptacles -2 and23 containing afresh supply of chemicals, and the'utility of such a rackas 18' is at onceappreciated.

It is also 1 found that the sediment of muddy waters will settle in thereceptacles 2, and assist in clarifying same. This in itself is a minormatter but this feature adds somewhat tothe utility ofthe device as awhole. p p p I have a specially prepared boiler'cornpound which I useinthe holderin soluble form, and the boiler compoundifs dissolved by theentrance and circulation of water in the interior of the holder, so thatthe solution passing through the perforations will permeate the water inwhich the device is readily appreciated.

The dispensation of the chemicals from both the inner receptacles2 intothe chamber of the barrel at 17, of the properly mixed chemicals andfluid from thebar'rel into the boileritself, may beaccelerated orretarded according to the capacity of the boiler, or the time period inwhich it is desired to replenish the chemicals of the device, by makinga greater or lesser number of perforations in the ends of theinner'receptacles, and the barrel; the methods above described thedevice canbe adapted to suit the capacity of various boilers,'and tocarry a boiler of any certainsizefover any desired time period withoutreplenishing the chemicals in the innerreceptacles of -'I imeperiodsofja month or more are common withffmy type of' boiler compound holder, duetothe'side 'wallsfof the inner receptaclesan d thej' holder itselfforming substantially closed compartments,

therebypreventing the wasting away of the chemicals, commonly occurringwhen holders having open sides and ends are used. With the latter typeconstant renewal of the chemicals is imperative, due to the latter nothaving protection from the direct action of the water, and the watercurrents within the boiler.

"With my type of holder, the objections above delineated are overcome,and it is seen that I have provided a boiler compound holder of markednovelty and utility for the purpose specified.

What I claim is 1. A boiler compound holder comprising an open endedbarrel, perforated plugs for closing said ends, and strips on said endsadapted to fold over and engage against said plugs for locking them insaid ends.
